SHANGHAI (Reuters) - Most U.S. firms in China currently have no plans to relocate production to other parts of the country or abroad due to the coronavirus, but there is less certainty about the long term due to growing worries over U.S.-China decoupling, a survey showed.

Concerns over logistics challenges now outweigh those of factory closures, said respondents to the joint survey by the American chambers of commerce in Beijing and Shanghai with consultancy PricewaterhouseCoopers. A total of 68% reported that demand for products and services was below normal.

"Our survey results show that companies are considering adjustments to their business strategy, but there is no mass exodus as a result of COVID-19," Ker Gibbs, president of the American Chamber of Commerce in Shanghai, said on Friday.

"Still, there is no escaping the fact that the current crisis adds a new and unwelcome dimension to the conversation about decoupling."

The novel coronavirus, which causes the respiratory illness COVID-19, was first reported in the central Chinese city of Wuhan late last year. It has led to over 130,000 deaths and caused massive disruption to economic activity around the world.

China has taken steps since February to restart its economy by recalling workers to factories and easing travel restrictions imposed earlier to help stop the virus spreading. On April 8, it eased a 76-day lockdown in Wuhan that cut the major industrial hub off from the rest of the country, after the number of new local infections plunged.

But the coronavirus is further testing ties between Washington and Beijing which are already strained over issues including trade, intellectual property rights and press freedom. U.S. politicians have accused China of withholding information about the virus while Chinese officials said the United States is trying to smear China.

TOO SOON

The survey was conducted from March 6-13 and received responses from 25 companies. It targeted senior executives from firms that had global revenue of over $500 million and were involved in sectors from healthcare to consumer goods.

Respondents were a subset of 70 companies polled in October for a prior survey by the three organisations, they said, providing a basis for comparison.

Noting how the top concerns for companies had shifted over the course of those two surveys, from the U.S.-China trade war to the coronavirus, the chambers said over half of their March respondents said it was too soon to tell whether their China supply chain strategy for the next three to five years would change.
